Hi Maxine, is this when you are signing in on the Shaw website in Firefox for Android? You get a popup asking for your device PIN, either once or over and over?

I had a problem trying to view my passwords this morning, where that screen got stuck in a loop asking for my device PIN. I had to restart my phone to recover. But I'm running the "Nightly" alpha test version of Firefox for Android, so hopefully that issue doesn't affect the main release.
